Hi,

If you have assigned an identifier to DiagramNode.Id property, you can find the node by calling Diagram.FindNodeById() method. The node's boundaries are returned by DiagramNode.Bounds property.

Hi,

Here's a code snippet that returns optional RectangleF value if the specified node exists -

Code
Select All
Function NodeBoundsFromId(ByVal id As Object) As RectangleF?
	Dim node As DiagramNode = Diagram1.FindNodeById(id)
	If node Is Nothing Then Return Nothing
	Return node.Bounds
End Function

Diagram1.Factory.CreateShapeNode(10, 10, 10, 10).Id = "1"
Dim r As RectangleF? = NodeBoundsFromId("1")
If r IsNot Nothing Then Debug.WriteLine(r)
